Fig. 3 illustrates the topology example of variable mirror 111, and Fig. 4 A and 4B show the example of the arrangement of electrodes of variable mirror 111.Variable mirror 111 shown in Fig. 3,4A and the 4B is by using the manufacturing of so-called MEMS (MEMS (micro electro mechanical system)) technology.
As shown in Figure 3, variable mirror 111 is equipped with upper substrate 201, infrabasal plate 221, the spring 251 to 254 (two ends of each spring respectively with upper substrate 201 with infrabasal plate 221 link to each other) relative with upper substrate 201 and the fulcrum (pivot) 261 that supports the approximate centre part of upper substrate 201.

In the variable mirror 111 of like this structure, can be applied to electric potential difference between top electrode 202 and each bottom electrode 222 to 225 by change, change the inclination angle of upper substrate 201 by means of electrostatic force with respect to infrabasal plate 221.Thus, change the inclination angle of reflecting part 204, made it possible to carry out image blur compensation.
The principle of the image blur compensation in the digital camera of present embodiment then, is described with reference to Fig. 5.
In Fig. 5, suppose that be that center from camera position A swing to camera position B with reference position S (for example position of user's shoulder) at digital camera between exposure period in the given time period.In this case, can determine rotational angle theta by the output signal of angular-rate sensor 104 is carried out integration.Yet because oscillation centre (reference position S) is away from camera, so angle θ is less than the angle for the treatment of actual correction.Therefore, need determine angle (θ+φ) by angle θ being added upper angle φ.
Can following steps determine angle φ: as abundant hour of θ, can by with 3-axis acceleration sensor 103 determine amount of movement b ' twice with X-direction output signal related integration, this amount of movement b ' is similar to the amount of movement b of the center of camera along the X-direction (see figure 1).Can by distance detecting unit 120 obtain between cameras and the object apart from a.In case determined amount of movement b ' and this apart from a, then can according to arctan (b '/a) try to achieve angle φ.Can (θ+φ) determines the correction inclination angle of mirror 111, makes it possible to carry out the correct compensation to image blurring by obtaining actual required correction angle by this way.
Can obtain by the automatic focusing operation of carrying out before beginning at image capturing with object apart from a.When for example 2kHz detected with sampling rate, sampling interval was 0.5 millisecond.The amount θ of rotation is fully little in 0.5 millisecond.Therefore, can carry out above-mentioned treatment for correcting with sufficient precision.
As mentioned above, according to present embodiment, calculate actual required correction angle by the output signal of using 3-axis acceleration sensor 103 and angular-rate sensor 104.Thus, even oscillation centre also can be carried out correct image blur compensation away from camera.
When camera is center when swinging with the wrist, that is, in the time of near oscillation centre is positioned at camera, the rotational component of swing plays a major role.Therefore, even only utilize the output signal of angular-rate sensor 104 to proofread and correct, also can obtain correction accuracy to a certain degree.3-axis acceleration sensor 103 is suitable for the corresponding output signal of acceleration on generation and three directions (directions X, Y direction and Z direction).In fact can not eliminate fully and crosstalk.Therefore, in the time of near oscillation centre is positioned at camera (for example at the wrist place), can only uses the output signal of angular-rate sensor 104 and do not use the output signal of 3-axis acceleration sensor 103 to come the calculation correction amount.Particularly, can take following method.
Whether to use 3-axis acceleration sensor 103 to come the calculation correction amount, only need for example to judge by controller 113 whether the output signal of 3-axis acceleration sensor 103 has predetermined value or bigger value.When the output signal of 3-axis acceleration sensor 103 during less than predetermined value, the rotational component of swing plays a major role.Therefore, only use the output signal of angular-rate sensor 104 and do not use the output signal of 3-axis acceleration sensor 103.In other words, when the output signal of 3-axis acceleration sensor 103 is not less than predetermined value, use the output signal of 3-axis acceleration sensor 103 and angular-rate sensor 104 to come the calculation correction amount.Thus, can carry out correct image blur compensation according to the type of rocking.
In order to make swing reduce to minimum to the influence of 3-axis acceleration sensor 103, it is desirable to 3-axis acceleration sensor 103 arrange as close as possible oscillation centre.When with the single-hand held camera, the user is handing shutter release button 102 1 sides of the camera main-body of camera.Camera mainly is the center swing with the wrist.Therefore, it is desirable to 3-axis acceleration sensor 103 is arranged near the part that operation holds during shutter release button 102.As shown in Figure 11, when with the single-hand held camera, it is following and be positioned at the outside of camera near shutter release button 102 1 sides that wrist is usually located at the bottom of camera.For 3-axis acceleration sensor 103 is positioned near the wrist as oscillation centre, therefore it is desirable to it be arranged in that XY plane (plane that comprises X-axis and Y-axis) is following, among the regional J (illustrating) on YZ plane (plane that comprises Y-axis and Z axle) the right with point.Preferably 3-axis acceleration sensor 103 is arranged among the right half of regional J1 (illustrating) of regional J with hacures.By being arranged in such a way sensor, in the time of near oscillation centre is positioned at camera, can reduce the influence of rotational component to 3-axis acceleration sensor 103.Therefore, accurately wobble detection makes it possible to carry out correct image blur compensation.
As mentioned above, when catching image when watching by view finder of camera, oscillation centre is positioned near the camera, such as wrist etc.On the contrary, when catching image when watching the LCD monitor 128 that is installed in the camera back side, oscillation centre is away from the shoulder of camera or ancon.Therefore, when oscillation centre is positioned at position away from camera, need to use the two output signal of 3-axis acceleration sensor 103 and angular-rate sensor 104 to come the calculation correction amount.Therefore, when LCD monitor 128 is in off working state, only use the output signal of angular-rate sensor 104 to carry out image blur compensation.When LCD monitor 128 is in duty, can use the two output signal of 3-axis acceleration sensor 103 and angular-rate sensor 104 to carry out image blur compensation.Thus, can judge oscillation centre definitely, make and to carry out correct image blur compensation according to the shooting situation.
In the situation of the swing of Z axle present embodiment has been described though be primarily aimed at rotating shaft parallel, needless to say be also can adopt in the swing of X-axis at rotating shaft parallel to use the same method.
[second embodiment]
Fig. 6 is the schematic perspective view according to the digital camera of second embodiment (image capture device).Fig. 7 is the block diagram of the digital camera of second embodiment.Because the essential structure of present embodiment is identical with first embodiment, therefore with identical Reference numeral represent with first embodiment in the corresponding parts of parts, and omission specifying to it.The many contents that to describe in first embodiment also are applied to present embodiment, therefore also omit specifying it.
Present embodiment is equipped with 3-axis acceleration sensor 103a and 103b.And, totalizer 140 is set, be added to together by the output signal of this totalizer 140 3-axis acceleration sensor 103a and 103b.3-axis acceleration sensor 103a has identical characteristic with 103b.
As shown in Figure 6, suppose the center of variable mirror 111 is arranged on initial point, the optical axis that points to variable mirror 111 centers from the center of first lens combination 106 is a Y-axis, the optical axis that points to the CCD112 center from the center of variable mirror 111 is the Z axle, the axle perpendicular with Y-axis and Z axle is X-axis, the surface level that comprises X-axis and Y-axis is the XY plane, and comprises that the perpendicular of Y-axis and Z axle is the YZ plane.Then, 3- axis acceleration sensor 103a and 103b are set to: make in them each be disposed in a zone of the correspondence in two zones that are arranged in diagonal positions in four zones being divided by XY plane and YZ plane.
Fig. 8 schematically shows foregoing.3- axis acceleration sensor 103a and 103b are arranged in respectively by among the regional A3 and A1 among four regional A1 to A4 of XY plane and the division of YZ plane.Certainly, 3- axis acceleration sensor 103a and 103b can be arranged among regional A1 and the A3.Ideally, wish Xa=-Xb and Za=-Zb, wherein Xa and Za are respectively the X coordinate and the Z coordinates of 3-axis acceleration sensor 103a present position, and Xb and Zb are respectively the X coordinate and the Z coordinate of 3-axis acceleration sensor 103b present position.
Here, consider that rotating shaft parallel is in the swing of Z axle.When oscillation centre was the Z axle, the absolute value of the output relevant with X-direction of 3- axis acceleration sensor 103a and 103b equated and its opposite in sign.Therefore, the result of the output addition in the totalizer 140 becomes zero.Therefore, addition angle φ (see figure 5) becomes zero, and the angle θ that tries to achieve according to the output of angular-rate sensor 104 becomes correction angle.When oscillation centre further away from each other during the Z axle, it is big that the addition result in the totalizer 140 becomes, and addition angle φ also becomes big.Therefore, be added to together, even under the situation of not carrying out complex operations, still can obtain actual required correction angle (θ+φ) definitely by output with 3- axis acceleration sensor 103a and 103b.
When the difference of the absolute value of the output relevant with X-direction of 3- axis acceleration sensor 103a and 103b during less than predetermined value, the rotational component of swing plays a major role.Therefore, in this case, can only use the output signal of angular-rate sensor 104 and do not use the output signal of 3-axis acceleration sensor 103a and 103b.In other words, when the difference of this absolute value is not less than predetermined value, can come the calculation correction amount by the output signal of using 3- axis acceleration sensor 103a and 103b and angular-rate sensor 104.
Therefore, present embodiment makes it possible to carry out correct image blur compensation according to the position of oscillation centre by using a plurality of 3-axis acceleration sensors.Particularly, can offset rightabout component of acceleration by arrange two 3-axis acceleration sensors in diagonal positions.Therefore, can under the situation of not carrying out the complex operations processing, carry out correct image blur compensation.
In the situation of the swing of Z axle present embodiment has been described though be primarily aimed at rotating shaft parallel, needless to say be also can adopt in the swing of X-axis at rotating shaft parallel to use the same method.
